3M™ Trizact™ Hookit™ Cloth Disc, 337DC, A160, 5 in x NH (127 mm x NH)

The 3M™ Trizact™ Hookit™ Cloth Disc 337DC provides fast scratch removal on automotive metal components and leaves a superior finish. Premium aluminum oxide macroreplicated grain on an X-weight backing combine to contribute a long product life and consistent performance for greater productivity.

The 3M™ Trizact™ Hookit™ Cloth Disc 337DC was designed for automotive white metal repair. It is ideal for blending and finishing minor defects and to remove scratch marks left behind by metal files or rotary tools. It provides a very fast scratch removal capability combined with a superior finish, leaving the surface ready for e-coat application. This cloth disc is available in grades of A300, A160, A100, A65, A45, A30, and 5-inch (127 mm) diameters, as well as make-to-order sizes. As the mineral breaks down, fresh mineral is exposed. The microreplicated pattern of the 3M™ Trizact™ Hookit™ Cloth Disc 337DC generates minimal heat. The open spaces between the abrasive bricks channel heat away and removes swarf. This means that the discs can be used on substrates like galvanized panels, aluminum hoods, and other applications where loading may be an issue. A 3M™ Hookit™ Attachment makes disc attachment, removal, and re-attachment clean and easy, and facilitates re-use of the disc for the extent of the abrasive life. It is simpler to attach a disc and it stays firmly seated. In addition, they are more flexible and they resist contamination by dust, dirt, and debris, unlike pressure-sensitive adhesive backings.
